Hello. My name is Luiza, I am a student of Computer Engineering in São Paulo, Brazil and I would like to ask for your help. As yesterday was the super pink moon day, I, at about 22:50, decided to take several photos of the moon using my phone and my non-digital telescope. And, analyzing the photos now, I realized that in some of them there are certain objects that I can't say exactly what they are. Could you help me identify them, please? I am not sure if they are satellites, ISS, Hubble, etc ... and I am very intrigued by themphotos.rar. P.S: the objects are in the lower left corner of the images

Hi! I'm Fran Not so long ago I took a picture of the ISS I never thought I was going to be able to get with the equipment I have. After saving for a long time, I was able to buy my first scope, an OTA Skywatcher 200P. I adapted it to be used in a dobsonian base because it was the cheapest way I had to get it to work. One night, I thought it might be cool to try to aim and record with my phone an ISS pass overhead. During the first attempt, I messed up the focus extremely bad but you can't imagine how happy I was to get a white blob in a frame that only I knew was the ISS. The following afternoon I tried again. This time the flyby was almost exactly overhead and the night was crystal clear. So I manually tracked the station looking through the finder scope and recording it with my phone at 1080p 60fps. Without much expectations I downloaded the files into my computer to review them. And was shocked with the results. The video was processed with PIPP, AutoStakkert and RegiStax. If someone told me the image was taken with a phone and manually tracked with a shitty dobsonian base I would not believe him! I got really lucky that night, but I can not be happier with the results. I believe I got to the edge of what I can accomplish with the equipment that I was able to buy. I'm not sure if ext step up should be a real camera or a mount. Anyway, any of them are too expensive If you want to see the frames before processing (and some nice shots of the moon that night), I'll leave a link to the video where I show them: Thank you so much for reading it all. Cheers, Fran

ISS taken with my 10" dob, asi 120 mcs camera and x 2 barlow. Followed the ISS with the finder scope across the sky whilst recording the AVI. This is a single frame brightened up.

It's difficult to get a sense of scale in this astronomy game; but we try. So here are 8 pics of the ISS passing between Vega and Epsilon Lyra last night - which is a second's worth of my Canon 7D firing off as fast as it can. The background is a single 30 second tracked exposure for a bit of context. Details: Esprit 100 prime focus/Canon 7D:1/1000s ISO1600 +30s background. The trick if you want to try this is to use planetarium software to find out exactly when the ISS will be near a bright object, then pre-align and focus on or near that object, then wait for the ISS to appear in the finder before letting the shutter go in rapid mode. I also optimised pre-focus on the computer using the focus feature on Nebulosity before switching the camera back to stand alone mode.

The sky is clear today and to top it, there was this wonderful ISS pass today. It has been awful the past days so I took my 15 year old out after doing chemistry HW (lots of protests!) and asked him (nicely!) to sit in a reclining deck chair with a pair of binos to watch the ISS pass overhead for 5 minutes! **** Apparently I'm the best dad in the world for today! **** I took the image below with a Nikon 7000 + 10mm Fisheye on a iOptron SkyTracker 2. Approx. 5 minutes exposure at ISO 800. I'm osrry about the read streaks. That is me with my red light wondering to/from the camera.

So as per the title it's a hello again! Apologies I've been gone a while (2yrs) due to work commitments and moving home. After visits to the Kennedy Space Centre this summer and having just returned from the National Space Centre in Leicester (kids sleepover party), I dusted off my trusty little Dob and managed to get some fantastic views of Saturn for the family and even watched the ISS go by. Astro fun reinvigorated, clear skies fellow loungers.

Hey all, I cannot believe my luck. I was out on the 31st July practicing imaging Jupiter and Saturn with the my new ADC and ZWO Asi224MC. All of a sudden the ISS started to appear from the South West heading East. I quickly released the clutches on the mount and followed the ISS the best I could with the finder scope. Everything was set in sharp cap for the Jupiter capture, ROI was set to 320 x 240, 2x barlow plus ADC. I could not believe it out of 6500 frames I manged to find 13 frames, which I stacked. Second bit of luck, PIPP said it could not find an object, so I turned the option off and it ran without errors. The hero was AutoStakkert which sorted the frames to the front of the ser file. Composite of 3 images from my night:

I took the best ISS images captured during yesterdays transit and ran them through Registax 6 to produce this image I think there are few artifacts present from the processing but I'm pleased with it

Always enjoy watching the ISS going over head. Always gets me that there are people living up there.

Hi Another attempt at the ISS. This time Canon 100d and 1200mm which actually is a 200 f4 with a 2x and 3x on it. Managed to bang off 50 frames when it was directly over head. What you get is a tiny little dot in the frame. (Currently given up trying to track it with the scope). Pipp to crop them all and then stack. First image is what I got from the stack of 50 drizzled at 3x, lots of CR which I got rid of by stretching the red away, then to B&W and play with registrax a lot. Result is second image. The lens is a very old M42 Pentacon 200mm but has very good optics, the teleconverter stack leaves a lot to be desired even for the £10 they cost me! So f24 1200mm @ 3200 ISO, 50 frames: half at 1/1000 half at 1/1600. I'm pretty pleased with the result. Please feel free to grab the png and play with the wavelets. Tom

This is the first time I've tried to view an ISS daylight lunar transit and to be honest I wasn't expecting to see anything, it came as a big surprise that the ISS was brighter than the moon I thought it was going to be a dim silhouette, maybe it was because the sun was at the same altitude 80 degrees away? Calsky had the mag as -2.5 Well I only just caught it at the bottom of the frame, Sanmatt also captured a widefield video of it and my wife saw it easily in binoculars, has anyone else tried this?

Hello, I got some pics of the ISS last night. First pass I got a few decent frames. Then there was a second, brighter pass but the ISS went into the Earth's shadow overhead so only half a pass. Bit overexposed but got some good frames. Put it into a gif. Manually tracked with my 200p, the stock 2x barlow (so f/10). ASI120MM. Gain around 59. Shutter speed around 2.7 ms. Processed with PIPP then virtual dub. Thanks, Dan

Decided to try a handheld shot of ISS tonight as it was coming close overhead. This is the best shot from about 20 taken. Quite pleased, definitely will try again. ED80 + TV Powermate x 2 + Camera, single shot ISO1600 1/400 sec.

Everything seems too perfect for now. There's an ISS transit of the sun on late Wednesday morning, visible not too far away from me. Two weather forecasts currently suggest it'll be clear skies then. What could go wrong? Well, the weather forecast is for almost 2 days away so there's plenty of time for it to be wrong. Also, I haven't managed to ask my boss yet if I can take an early lunch to catch it... I need to plan where I want to see it from, the ground track passes through the Cotswold water park and there's various car parks in there I could try. Since I will be imaging from a car park, I can take more kit than I did for the Venus transit previously, and will go with both Ha and white light kit. So rig 1 will be PST capturing continuous video. Rig 2 will be DSLR with solar filter... but I'm not so confident in getting the timing just right for this one as it's only 0.8 second window!

I managed to capture a Lunar transit on the 28th March and to say it was my first go and I had 20 minutes notice, I think I did pretty good!

Even the ISS comes to the Baron Resort in Sharm el Sheik

Hello, I did a topic before about imaging the space station but I thought I would start a new one. Last night I managed it for the first time, I focussed on Jupiter and adjusted settings on there as well. I adjusted it until Jupiter was correctly exposed. However the ISS was definitely overexposed. Its grey as I have just lowered the brightness. What I am wondering is, yes I am going to use a shorter shutter speed later, but how would an IR pass affect it? It would certainly improve the exposure, but any side effects from an IR pass on a satellite? Dan

I have written a blog post about imaging artificial satellites, with a focus on the ISS. Since the SGL challenge is precisely about that, it thought it could be interesting to share. The article is there: https://satelliteobservation.wordpress.com/2017/04/20/observing-satellites/ It has a bit of background in the beginning on satellites and how imaging a satellite is similar to a satellite imaging the ground, plus some discussion about the different types of mount and tracking and of what limits imaging performance. The conclusion is that a dob + a high-speed, high resolution camera is a good way to go to make images like these: There are some very nice images from other people in there too.

My first attempt at the ISS - harder than I thought and much smaller, I would like to get in closer eventually. Dug the 150PDS out and 650D, 1 x 1/1250 at 3200 iso and a little tweak in PS, manually tracked. Short session but it was worth it
